How to make sure Radarr doesn't snatch full Blu-Rays (ISO/BDMV)
Radarr has issues in separating full BluRays from BluRay-RIPs, after some research and testing, I found a way to solve this issue. To make this work, we need to make use of Custom Formats, and make sure the profile used is utilizing it.
Custom Formats
Navigate to Settings => Custom Formats
Then, click on 
to add a new Custom Format.
On the new popup at the bottom, under Advanced, click on Custom
A new popup will appear.
Enter the following info:
Name => BR-DISK
Format Tags => C_RXRQ_(AVC|VC-1|HEVC) M_N_REMUX S_N_WEBDL
!!! NOTE: make sure the 3 tags are entered separately !!!
Quality Profiles
Then, go to your used profiles. Scroll down to the bottom where you see Custom Formats.
Make sure you uncheck your newly created Custom Profile BR-DISK
Make sure to do that with all your used Quality Profiles.
